FIG. 2 is a perspective view of an assembly of preferred embodiment of the present invention; and

FIG. 3 is an exploded of a preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

The technical characteristics and objectives of the present invention can be further understood by the following detailed description of preferred embodiments and related drawings.

Firstly, the air-conditioning vent structure used in the air-conditioning vent vane switching structure of this preferred embodiment is introduced as follows.

In FIGS. 1 to 3, the air-conditioning vent comprises the following elements:

A grating panel 1 includes a grating 11 formed thereon, and a slide hole 12 formed on the grating panel.

A frame 2 is installed on a wall and disposed on an inner side of the grating panel 1 to serve as a connecting base of parts including a grating panel, a vane and a driving plate, wherein the frame has a rectangular framework structure.

A plurality of vanes has both ends sequentially and rotatably coupled to two opposite lateral surfaces of the frame, wherein a connecting shaft 31 is disposed at an edge of the same ends of these vanes.

A connecting plate 4 is disposed at a position corresponding to the connecting shaft 31 and fixed to the connecting plate 4, and the connecting plate 4 further includes a connecting hole 41 formed thereon. In this preferred embodiment, a larger circular hole is formed at the center of the connecting hole, and two long holes are formed on both sides of the circular hole respectively.

With reference to FIGS. 1 to 5 for an air-conditioning vent vane switching structure of a preferred embodiment of the present invention, the air-conditioning vent vane switching structure comprises the following elements:

A push button 5 includes a push plate 51 disposed on an external surface of the grating panel and a connecting portion 52 passing through the slide hole 12 formed on an inner side of the grating panel inner side, wherein the connecting portion has a shaft hole 53 formed thereon, and the whole push button structure of this preferred embodiment is integrally formed, and the push plate in the push button can be fixed to the connecting portion by any conventional connecting method.

A link rod 6 is provided for coupling the push button and the link rod. An end of the link rod has a shaft 61 received by the shaft hole 53, and the shaft 61 has a groove 62 formed thereon for separating the shaft into a first portion and a second portion, and a wedge-shaped member 63 is disposed separately on outer sidewalls of the first portion and the second portion. The other end of the link rod has a protruding shaft 64, and the protruding shaft 64 has two bar-shape baffles 65 disposed on two opposite sidewalls of the protruding shaft 64. In this preferred embodiment, the protruding shaft 64 and the baffle 65 are integrally formed.

In the assembling process, the shaft 61 and the protruding shaft 64 at both ends of the link rod together with the baffle 65 are plugged into the corresponding shaft hole 53 and connecting hole 41 to complete the assembling process of the switching structure. With the design of the groove 62, the first portion 611 and the second portion 612 as well as the wedge-shaped member for connecting the two can be compressed and deformed in a direction towards the groove, so that the shaft can be plugged into the shaft hole easily. After the plugging, the wedge-shaped member is elastically restored into the shaft hole, so that the link rod will not be separated from the push button by external forces easily. After the protruding shaft 64 and the baffle 65 are plugged into the connecting holes, the baffle 65 can be rotated to block the connecting plate, so as to achieve the effect of securely coupling the link rod and the connecting plate. In this preferred embodiment, the protruding shaft can be rotated with respect to the link rod, so that when the baffle 65 is rotated, the protruding shaft 64 is also rotated accordingly.

The operating principle of the air-conditioning vent vane switching structure is described as follows:

When it is necessary to open the vane for ventilation, the push plate on the grating panel is pushed, and the push plate drives the connecting portion to slide altogether in the slide groove, and an end of the link rod has a lengthwise displacement occurred during its rotation with respect to the shaft hole 53, so that the other end of the link rod pushes the connecting plate to move and drive the vane rotate in order to open or close the air-conditioning vent.

Obviously, the air-conditioning vent vane switching structure has the advantages of reduced components, simple structure, easy assembling process, high production efficiency, labor-saving operation and good hand feel.
